Application filed June 10, 1915. Serial No. 33,267.

To all whom it may concern.

Be it known that I, JOHN IRVINE, a citizen, of the United States, and a resident of Iii-- dianapolis, county of Marion, and State of Indiana, have invented a certain new and useful lnternal-Combustion Engine; and I do hereby declare that the following is a full, elcaryand exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

This invention is to improve the operation of internal combustion engines, particularly in the matter of supplying mixture to the cylinder or cylinders of the engine and exhausting the same therefrom and to simplify and render more compact the construction of internal combustion engines.

One feature of the invention resides in the valve construction for controlling the intake and exhaust; a single valve being used for both purposes.

Another feature of the invention consists in carbureting the mixture in the valve for controlling the intake and exhaust and thus doing away with the carburetor, as such.

This makes a very compact engine, in which a single valve structure located ad-- jacent the engine cylinder performs three functions, carbureting or preparing the mixture, controlling the intake into the cylinder, and controlling the exhaust therefrom.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a central vertical section of an internal combustion engine equipped with said invention and having two cylinders, the section line being be tween said cylinders. Fig. 2 is a horizontal section through the engine on line 22 of Fig. 1. Fig. 3 is a perspective view of the valve bushing. Fig. 4 is a perspective view of the valve. Fig. 5 is a section on the line 5 5 of Fig. 2 showing the. valve in the intake position for one cylinder. Fig. 6 is a section through the engine on the line 66 of F ig. 5, showing the valve in position to permit the intake into one cylinder and the exhaust from the other cylinder. Fig. 7 is the same as Fig. 6 with the valve further operated so as to shut off the intake altogether but exhausting from one cylinder. Fig. is a plan view of a portion of the upper pa rt of Fig. l.

In detail. the device shown in the drawings to illustrate the general nature of the invention, an engine having twin cylinders l0 and ll with a common water jacket- 12 supplied through a pipe 13.

Within the surrounding water jacket 12. to one side of the cylinders and on a line be tween them, as shown in Fig. 2, there is a valve casing 1i stationary and adapted to receive the removable valve bushing 15, which is cylindrical with its lower end resting on a lip 16 on the valve casing, and its upper end having a shoulder 17, see Fig. 3, adapted to rest on the shoulder 18 and the. inner wall of the valve casing. Said bushing 15 is sta tionary and held so by a groove 19 in the shoulder 17 interlocking to the corresponding projection of the valve casing; The valve bushing has two ports 20 and 21 which conimunicate with the corresponding ports 22 and 23 leading to the two cylindei as shown in Fig. (i. The foregoing parts are all fixed in position. There is also an exhaust outlet 25 in the engine casing leading from the lower open end 26 of the valve bushing see Fig.

The valve, for controlling the intalie and exhaust. has an external cylindrical wall 27 and an inner hollow conical member 28 flaring downward and outward to the outer wall at the bottom, and with the open lower end 29 of said conical valve member in communication with the open lower endQi'S of the valve bushing 15 and the exhaust outlet 25.

The conical member 28 of the valve does not extend as high as the outer wall 23'' and is secured on the shaft 30 which is vertical and extends centrally through the openings 26 and 29 and through a bearing 31 in'the engine casing and is driven by a worm gear 32 thereon and meshes with the worm gear 33 on a horizontal shaft 34. which is driven by the. crank shaft of the engine and inter mediate means, not shown. This causes the. valve to c i.-ntinually rotate.

The upper end of the valve has a shoulder 35 resting on a corresponding shoulder 36 and the inner wall of the bushing 15. and the lower end of said valve rests upon an hashing so hush therefore.

The other in he rahe is loea rd within the \vh inav lie (ll li l the exhau t r;.. ier. and l is in (oililifliiliCiv tiou interv 2i with the 7 ;lilulel's through an erzhzuisi port l l. ie Figs. 1 and Said cxhnu-i min.

These poi-U and I") are of the same size and same distanee apart as the ports 0 and 21 in the r-lvr in ring: and the ports and 23 of the cylinders. vhieh are 590' apart.

The mixture i lied when the carburetingl i=1 s iaee ithin the valve or what has been turned. the intake ehainher. The ir emers the -ill' inlet i and passes through an air heated elnnnher ll on top oi the c vl inders into the valve ehainlier. This air inlet is -ontz=olled ii) an air va ve 42 operated by a lever 43 and other suitable connections n t shown. The upper end ol the main valve for rontrolling the intake and exhaust is closed by a rap 47 having centrally in a. hearing l8 on the upper end oi the shaft 330. There is also a fuel nozzle to extending through said rap and direeted downwardly so to supplv the int-oozing fuel which pass s downwardly aerosithe path oi air entering the ralve chamber. Fuel is sup plied through some suitable source of supply through the pipe t and is controlled by the needle valve ll). This needle valve has an arm 501m it eonnected hv a link iii with the air valve member 1 5 so that the actuation of the latter will cause a eorrespoiuh ing: operation ol' the needle valije.

Normally when the engine is heated, the air ialve and needle valve stun-1i almost closed. but partially open. so lieien! to sup plv the engine. when it is not pulling, a load. \l'lu-n it is desired to llll'i"'l. the 'peed or power of the engine. th v lezer l3 i drawn so as to in rease theflllillh hl li all air and l'uel proportionate!v and this movement v r-oiuiuue until the limit of the capacity of the engine is reach d. at which time the air valve 42 will he in a horizontal position and the needle valve opened eorrrspon lingrlv. la other words in this engine tllu mivlure eontrolled in advance. that is. by eoutrolliug the supplv ol air and fuel separately lint simullam-zmslv and proportion atelv. instead of controlling: the sup 'il v oi inivture to the engine alter he mixture has been formed, by n was of throttle llte in each e vlinder there i a piston and a piston Will 51 eonneeted crank shalt not shown The operation will he the 'nllowint' explanation: .\s shown in lg: f) when the valve in one position. the mixture will he supplied to one cylinder while a quarter turn oi the valve to the position shown in Fig. 7 will close the cvliniler which has just been suppliedwith mixture and in it the compression stroke will be taking place. in the other cylinder which \Viis, previouslv exhausted. mixture is now entering as its piston is moving downward. hen the valve is given another quarter turn. not shown, the, explosion will take place in l; :e first mentioned evlinder 10 and while the mixture is being compressed in the other e linder 11.. in the last quarter turn of the valve. not shown, the cvlinder 10 will exhaust and the explosion will take place in the ey'linde-r 11. This evele will be repeated during" the operation of the engine.

While the invention is shown in connec tion with an engine having two cylinders. still it is not intend d to be limited for it can he used in connection with one or with 21v number of oviindeis.
